The U.S. adopted all kinds of laws in the Great Depression, including laws against overtime work and pay. Most of these laws were targeted at Keynesian stimulus and creating jobs, and few had anything to do with ethics or morality (though these latter concerns may have played supporting roles). I am not a Randian, but there is nothing wrong with taking benefits from a system which had (in her view) wronged her. If I steal some things you need, then offer you some of them back, acceptance of my offer is not tantamount to forgiveness, and does not condone or justify my behaviour. I am no Rawlsian, and the 'veil of ignorance' assumes that everyone would agree if only they were not self-interested; the only problem with this is that it's not true. There is much more variance of moral belief within each class/gender/nationality/race than across them.
